The system of the disclosed invention utilizes flight plans and coverage data to provide users aboard aircraft with status of satellite Internet services. The system couples the flight plans with the coverage data to provide information regarding how the flight path of the aircraft will affect availability of Internet services during the flight. The method includes retrieving a flight plan to generate a flight path having one or more waypoints, transmitting one or more service coverage data from service providers, coupling the flight path with the service coverage data to determine portions of the flight path in which the network service is unavailable, and delivering to the users information about the service unavailable portions of the flight path.

RELATED APPLICATIONS

This application is a Continuation In Part (CIP) of U.S. non-provisional patent application Ser. No. 16/458,936 entitled “SYSTEM AND METHOD FOR FORECASTING AVAILABILITY OF NETWORK SERVICES DURING FLIGHT”, filed in the USPTO on Jul. 1, 2019, which issued as U.S. Pat. No. 10,939,304 on Mar. 2, 2021, the disclosure of which is hereby incorporated by reference in its entirety, and which claims priority of U.S. Provisional Application Ser. No. 62/691,883, entitled “AIRCRAFT CONNECTIVITY FORECASTING SYSTEM,” filed on Jun. 29, 2018, the disclosure of which is also herein incorporated by reference in its entirety.

TECHNICAL FIELD

This invention relates to aircraft communications, and in particular to systems, devices, and methods for determining how an aircraft's flight path will affect the availability of Internet services of aircraft passengers while the aircraft is flying, which provides solutions that reside within a customer portal and provides a visual indication of whether an aircraft may expect to have an internet connection along their flight path.

BACKGROUND

Passengers on aircraft, especially private aircraft, are increasingly using Internet services for their digital devices, such as for their smart phones, tablets, laptop computers and the like. A problem occurs when the Internet service of the passengers is interrupted and dropped without any notice to the passengers before the interruption occurs. These disruptions to service have caused loss of communications between the aircraft passengers and other parties. Additionally, these interruptions have resulted in losing data on the digital devices of the passengers, such as losing drafted work products such as draft documents, and the like. Thus, the need exists for solutions to the above problems.

SUMMARY

An advantage of embodiments described herein is to provide systems, devices, and methods for determining and forecasting how an aircraft's flight path will affect the availability of internet services of aircraft passengers while the aircraft is flying. Another advantage of embodiments described herein is to provide systems, devices, and methods for providing a visual indication to passengers aboard an aircraft of whether the aircraft may expect to have an internet connection along their flight path. Further objects and advantages of embodiments described herein will be apparent from the following detailed description of the presently preferred embodiments which are illustrated schematically in the accompanying drawings.

These and other advantages may be provided, for example, by a connectivity forecast system to provide users aboard aircraft with status of network services. The connectivity forecast system communicates with one or more service providers. The connectivity forecast system includes a non-transitory or other physical storage medium to store non-transitory computer readable and executable instructions in communication with one or more processors to execute the executable instructions, and to retrieve and store information, that cause the one or more processors to perform the functions of the system and method described herein, including operations to provide the status and connectivity forecast of the network services. The operations may include any, all or any portion of the following in any combination: retrieving a flight plan to generate a flight path; retrieving one or more service coverage data from the service providers; retrieving or storing information about the service providers such as bandwidth, cost, or reliability and storing such information in the storage medium; receiving a priority assignment for all or a portion of the service providers; coupling the flight path with the service coverage data to generate an integrated flight path that indicates service available and unavailable portions of the flight path; providing the connectivity forecast display information of the system through a web portal such that a user having an electronic device may communicate with a processor of the system via the web portal, for example via the Internet accessing a web address such an Internet Protocol (IP) address, for the purpose of retrieving from the system the connectivity forecast display information of the system and displaying the connectivity forecast display information on a display of a user electronic device; and, in embodiments, displaying an integrated or segmented flight path as part of the connectivity forecast display information. The flight path may include one or more waypoints. The one or more service coverage data is transmitted from the service providers and the service coverage data may include a plurality of sub-coverage data.

The operations may further include updating the one or more service coverage data from the service providers during flight. The coupling the flight path may include interpolating the waypoints to generate intervening waypoints between waypoints. The coupling the flight path may include selecting sub-coverage data that cover regions in which the flight path is formed, determining sub-coverage data, among the selected sub-coverage data, which indicate unavailability of the network services, and determining portions of the flight path in which the network service is unavailable. The determining portions of the flight path may include finding new or more waypoints that are not covered by any of sub-coverage data indicating network service availability. The operations may further include checking changes of the one or more service coverage data periodically or upon receiving information from the service providers during flight, checking changes of the flight plan during flight, updating the one or more service coverage data and the flight plan based on the changes during flight, and updating the integrated flight path based on the updated one or more service coverage data and flight plan.

The connectivity forecast system may further include a display device, and the displaying the integrated flight path may include displaying the integrated flight path on the display device. In embodiments, the display device may be a display of an electronic device that is in communication with the one or more processors of the system directly or via any network or communication interface as is known in the art, such as, for example, through any Internet connection, wireless interface (such as IEEE 802.11, Bluetooth®, Zibgee® or any other wireless connection) or wired interface (such as, for example, Ethernet) or any combination of such networking and communication systems. As a non-limiting example, a user's electronic device may comprise a display device, a processor, a physical media memory and a human user interface in communication with one another, the physical media memory containing non-transitory computer readable and executable instructions, and circuits, for receiving input data and commands from a user such as a keyboard, touchscreen, microphone for receiving voice commands, or other human interface elements as are known in the art, that is in communication with a processor of the system through any wired or wireless connection, such as, for example only, through a wireless router, or through any satellite, ground-to-air or other data link. Thus, as a non-limiting example, a passenger or user in flight may utilize any electronic device having such processing, communication, human interface and display features such as a laptop, electronic tablet, smart phone or computer to communicate with a processor of the system, for example via a web interface, for the purpose of receiving information from the connectivity forecast system of the invention and displaying such information on the display of their electronic device while the aircraft is in flight, or while the aircraft is on the ground. In embodiments, the system of the invention is web-based, meaning that any electronic device that is in communication with a processor of the system may access the web address of the system, using any wired, wireless or optical communication system and interface, for the purposes of receiving connectivity forecast display information as described herein from a processor of the system and displaying such connectivity forecast display information on a visual display of the user's electronic device.

The connectivity forecast system may communicate with global positioning system (GPS) to identify a current location of the aircraft during flight. The current location of the aircraft may be shown on the displayed integrated flight path. The connectivity forecast system may communicate with a flight operator to retrieve the flight plan.

These and other advantages may also be provided, for example, by a method for providing users aboard aircraft with status of network services. The method includes retrieving a flight plan to generate a flight path, transmitting one or more service coverage data from service providers, storing the service coverage data in database or one or more memories, coupling the flight path with the service coverage data to generate an integrated flight path that indicates service available and unavailable portions of the flight path, and displaying the integrated flight path. The flight path includes one or more waypoints. The service coverage data includes a plurality of sub-coverage data.

The method may further include updating the one or more service coverage data from the service providers during flight. The coupling the flight path may include interpolating the waypoints to generate intervening waypoints between waypoints. The coupling the flight path may include selecting sub-coverage data that cover regions in which the flight path is formed, determining sub-coverage data, among the selected sub-coverage data, which indicate unavailability of the network services, and determining portions of the flight path in which the network service is unavailable. The determining portions of the flight path may include finding one or more waypoints that are not covered by any of sub-coverage data indicating network service availability.

The method may further include transmitting information including a current location of the aircraft from GPS during flight. The displaying the integrated flight path may display the current location of the aircraft on the displayed integrated flight path. The method may further include checking changes of the one or more service coverage data periodically or upon receiving information from the service providers during flight, checking changes of the flight plan during flight, updating the one or more service coverage data and the flight plan based on the changes during flight, and updating the integrated flight path based on the updated one or more service coverage data and flight plan.

Further, the system and method of the invention may operate to cause the aircraft flight path to be graphically displayed, or otherwise presented, as a series of segments superimposed on a map in which each segment represents a portion of the flight path, indicating the highest priority service provider available, if any, for each segment. This may be desirable in cases in which a plurality of service providers are able to provide network services along the flight path, each service provider having unique coverage and other characteristic(s) such as bandwidth or cost. In such cases, a priority scheme may be utilized by the system and method of the invention to assign a unique priority to each service provider relative to the other service providers, such priority being based on a desired characteristic (for example, bandwidth), determine the highest priority service provider available for each segment of the flight path, where a segment is defined as portion of a flight path that has a differing highest priority available service provider than a preceding portion of the flight path, and display segments of the flight path using an identifier that uniquely identifies a specific service provide (for example, line color, line width, line type, associated graphic symbol, or other unique graphic identifier) that identifies the highest priority available service provider for that segment; or, alternatively, for those segments in which no service provider is available, displaying such “no service” segments in a unique identifier that identifies that segment as having no network services available. In embodiments, the entire flight path, from source to destination, may be displayed in such segments, or in embodiments, only a portion or multiple portions of a flight path may be displayed in such segments. Portions of the flight path for which no service is available may be displayed in segments in a unique identifier (for example, line color, line width, line type, associated graphic symbol, or other unique graphic identifier) that represents and identifies that no service is available for that segment.

DETAILED DESCRIPTIONS

It is to be understood that the figures and descriptions of the present invention may have been simplified to illustrate elements that are relevant for a clear understanding of the present invention. It is also to be understood that the drawings included herewith only provide diagrammatic representations of the presently preferred structures of the present invention and that structures falling within the scope of the present invention may include structures different than those shown in the drawings. It is also to be understood that the invention is not limited in its applications to the details of the particular arrangements shown since the invention is capable of other embodiments. Also, the terminology used herein is for the purpose of description and not of limitation. In the Summary above and in the Detailed Descriptions and in the accompanying drawings, reference is made to particular features (including method steps) of the invention. It is to be understood that the disclosure of the invention in this specification does not include all possible combinations of such particular features. For example, where a particular feature is disclosed in the context of a particular aspect or embodiment of the invention, that feature can also be used, to the extent possible, in combination with and/or in the context of other particular aspects and embodiments of the invention, and in the invention generally.

In this section, some embodiments of the invention will be described more fully with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime notation is used to indicate similar elements in alternative embodiments.

With reference to FIG. 1, shown is a view of a flight plan visualized on a map. Before flight, flight operators, such as airliners, may provide flight plans so that the flight plans may be used in the aircraft during flight. These flight plans contain a starting point 101, an ending point 102, and waypoints 103 between the starting and ending points. These starting and ending points 101 and 102 and the waypoints 103 may be represented by latitude and longitude points (coordinates). The flight plan may be provided by a third party, or may be created by flight crews. The flight plans may be retrieved from databases of the flight operators or the third party, or from a database in the aircraft such as a database included in a flight deck system. The flight plan may be created by the flight operators or flight crews aboard the aircraft. The flight plan may be created using a third-party flight-plan software program and retrieved from that program.

The flight plan may comply with rules and regulations of controlling airspaces of regions through which the aircraft may pass. The latitude and longitude points of the flight plan may be visualized as a flight path on a map. FIG. 1 shows an exemplary flight path with a starting point 101, ending point 102, and a plurality of waypoints 103 connecting the starting point 101 to the ending point 102. The starting point 101 may be an airport from which aircraft departs, and the ending point 102 may be a destination airport.

Satellite Internet providers may supply coverage data for their partners in certain formats such as keyhole markup language (KML) files. These files provide shapes representing geographical areas. The coverage data may include global geographical regions in which services are available. The coverage data may be represented on a map as coverage maps visualizing geographical regions in which the satellite Internet services are provided. However, the coverage data may include local areas in which satellite Internet services are disabled temporarily or for a certain time period. The coverage data may include a plurality of sub-coverage data that may include further specific information such as service availability, geographical regions which the sub-coverage data cover, and attribute of the services such as strength of data signals and data transfer speed. The sub-coverage data may be represented on a map as coverage cells. FIG. 5 shows exemplary coverage cells 521 and 522 that are represented in oval shapes. FIG. 7 shows exemplary coverage cells 700 that are represented in honey-comb shapes (FIG. 5 actually shows a combination of oval-shaped and honey-comb shaped sub-coverage cells; the different shapes may represent Internet coverage data of different satellite Internet providers). The sub-coverage data, and therefore the coverage cells, may be deployed to overlap each other, so that satellite Internet services and/or information about availability of the Internet services may be continuously provided while aircraft passes from one coverage cell to another coverage cell. The coverage data may be provided by satellite Internet providers before flight or during flight, through communication, by embodiments of systems, devices, and methods for determining and forecasting how an aircraft's flight path will affect the availability of internet services of aircraft passengers described herein, with the satellite Internet providers, to continuously supply updated coverage information during flight.

With reference to FIG. 2A, shown is an exemplary initial coverage map where coverage data is transformed into a visualization of spatial coverage data. This data may be stored in a database as spatial data and the spatial coverage data is visualized on a map. This spatial data map signifies the full capability of the coverage range of the satellites. FIG. 2B shows an exemplary outage map where outage data, which indicate no coverage, are transformed into a visualization of outage data which is stored in a database as spatial data and the spatial outage data is visualized on a map. This spatial outage data map signifies the areas that are known to have no service coverage. FIG. 2C shows an exemplary true coverage map in which the initial coverage map and the outage map, which are stored in the database as spatial data, are combined to provide status of service that may include geographical regions in which the services are available.

The connectivity forecast system of the disclosed invention utilizes flight plans and coverage data described above to provide flight crews or passengers aboard the aircraft with status of satellite Internet service availability during flight, which enables to forecast whether the aircraft is approaching a service unavailable region and to estimate when the service would be unavailable. For this purpose, the connectivity forecast system couples the flight plans with the coverage data and also with current location of the aircraft to determine service availability through the flight path.

With reference to FIG. 3, shown is a diagram that illustrates the connectivity forecast system interacting with service providers and flight operators. With reference to FIG. 4, shown is a diagram illustrating hardware elements of the connectivity forecast system. The connectivity forecast system 330 may be carried by or equipped in aircraft 310 during flight. The connectivity forecast system may be included in a hand-held device or may be fixedly equipped at a flight cockpit deck system. The connectivity forecast system 330 may communicate with the flight operator 350 to retrieve flight plans from a database of the flight operator. If the flight plan is created by flight crews and stored in a device such as flight deck system 320, the connectivity forecast system 330 may retrieve the stored flight plan from the flight deck system 320. The flight plan may be created using a third-party flight-plan software program and retrieved from that program. The retrieved flight plans may be stored in storage medium 332, such as memories, or database 336 of the connectivity forecast system 330. The connectivity forecast system 330 may convert the retrieved flight plan data into coordinate data, or otherwise determine coordinate data from the retrieved flight plan, that allows the connectivity forecast system 330 to determine the geographic location of the beginning of the flight path, each waypoint on the flight path, and the end of the flight path. If the flight plan is changed during flight by the flight operator or flight crews, the connectivity forecast system 330 updates the flight plan. The connectivity forecast system 330 communicates with satellite Internet service providers 360 to retrieve service coverage data. The connectivity forecast system 330 may communicate with systems such as servers or databases of the Internet service providers 360 to retrieve service coverage data. This communication with the service providers may be performed in real time to update the coverage data as soon as the updated coverage data is available from the service providers. The retrieved service coverage data may be stored in the storage medium 332, such as memories, or database 336 of the connectivity forecast system 330. These retrieval processes of the flight plans and coverage data may be performed wirelessly or by wired connections through the networking adaptor 333 or input/output adaptor 334 of the connectivity forecast system 330.

During flight, the aircraft 310 may communicate with satellite systems 370 to obtain flight information related to the flight operation such as current location of the aircraft. The flight information received from the satellite system 370 may be stored in a device such as the flight deck system 320 of the aircraft 310. The connectivity forecast system 330 may maintain communications with the flight deck system 320 during flight, and some of the flight information may be transferred to the connectivity forecast system 330 through the networking adaptor 333 or input/output adaptor 334. Alternatively, the connectivity forecast system 330 may directly communicate with the satellite system 370 or ground systems (not shown) to obtain necessary flight information such as the current location of the aircraft. The connectivity forecast system 330 may communicate with global positioning system (GPS) to find the location of the aircraft 310 that carries the connectivity forecast system 330. This location is preferably displayed on the flight path and updated throughout the flight.

Referring to FIG. 4, the connectivity forecast system 330 includes one or more storage media 332 that may include memories and/or hard disk drives. The storage media 332 store software or computer programs including instructions that perform necessary processes, when executed by one or more processors 331, to provide availability of satellite Internet services. The connectivity forecast system 330 may include display device 335 to display information related to status of the services and other flight information. The display device may be in communication with one or more processors of the system. The connectivity forecast system 330 may visualize the aircraft's projected or planned flight path that is generated by using the flight plan, and may display current location of the aircraft on a map. The connectivity forecast system 330 may display service coverage map that is generated by using the coverage data. The flight path is coupled with the coverage map to visualize portions of the flight path in which the services are available. These portions of the flight path may be color coded according to the availability of Internet services along the flight path. Alternatively, these portions of the flight paths may be shown by other representations, such as but not limited to showing connectivity in solid lines, dotted lines, and the like. When the connectivity forecast system receives multiple coverage data from different service providers, the multiple coverage data may be visualized as multiple coverage maps with different color codes or with different visual representations. FIG. 5 shows exemplary two coverage maps 520 and 530 that includes oval shaped coverage cells and honey-comb shaped coverage cells, respectively.

The connectivity forecast system of the disclosed invention couples the flight plans and the coverage data to provide status of service availability during flight or on ground, and to forecast service availability through flight path based on current location of aircraft that carries the connectivity forecast system.

In embodiments, connectivity forecast system 330 may monitor the actual Internet connectivity of the airplane on which connectivity forecast system 330 is operating. Connectivity forecast system 330 may store this actual Internet connectivity data and transmit it, e.g., through an Internet connection, to other connectivity forecast systems 330 operating on other airplanes.

Consequently, connectivity forecast system 330 may also receive feedback data from other connectivity forecast systems 330 operating on other airplanes about the actual Internet connectivity experienced by other airplanes operating along or near the flight path of the airplane on which connectivity forecast system 330 operates. Consequently, connectivity forecast systems 330 may use this data for calculating and visualizing Internet connectivity.

With reference to FIG. 5, shown is an exemplary screen illustrating flight plans and coverage data that are coupled together and visualized on a connectivity visualization map 500 as flight path and coverage maps, respectively. FIG. 6 shows an detailed exemplary illustration of a flight path and coverage maps coupled together. The screen in FIG. 5 shows two coverage maps 520 and 530 each of which cover global geographical regions. The two coverage maps 520 and 530 may represent different service provides or different data services from the same service provider. FIG. 5 shows two coverage maps (i.e., spatial coverage data for two satellite Internet providers), but the number of coverages maps are not limited. One or more coverage maps may be coupled with the flight plans, and may be displayed in the display device 335 of the connectivity forecast system 330. The first coverage map 520 is represented with oval shape coverage cells 521 and 522, and the second coverage map 530 is represented with honey-comb shaped coverage cells. The coverage cells 521 represent areas where satellite Internet services are available, and the coverage cells 522 represent areas where the satellite Internet services are not available. In an embodiment, the coverage cells 521 and coverage cells 522 are color-coded with different colors to indicate availability (e.g., the coverage cells 521 may be green) and lack of availability (e.g., the coverage cells 522 may be red), respectively. FIG. 5 also shows an integrated flight path 510 in which flight path is coupled or integrated with the coverage map 520, details of which are shown in FIG. 6. The integrated flight path 510 is generated to visualize service available flight path and service unavailable flight path. The integrated flight path 510 includes portions of the flight path in which Internet services are available 511 and portions of the flight path in which Internet services are not available 512. Like the coverage cells 521 and 522, the portions of the flight path 510 and 511, may be color coded to indicate on which portions Internet services are available (e.g., portions 511 may be green) and which portions Internet services are not available (e.g., portions 512 may be red).

In an embodiment, the minimum size of the portions 511 and 512 illustrated on the flight path 510 may the distance between any two consecutive waypoints on the flight path 510.

Alternatively, the connectivity forecast system 330 may calculate additional coordinates on the flight path 510, determine Internet availability between such additional coordinates, and depict portions 511 and 512 between such coordinates, thereby displaying smaller portions 511 and 512 and greater granularity. Additionally, Internet availability on the flight path 510 may not be a binary available/not available between each waypoint or additional coordinate; for example, location of a flight path on a boundary between available coverage cells 521 and unavailable coverage cells 522, local weather conditions, and/or other factors may impact Internet availability on a more granular level then can be displayed by coverage cells 521 and 522 and portions 511 and 512. The connectivity forecast system 330 may calculate such coverage forecast using interpolation algorithms to generate intervening waypoints (additional coordinates) between waypoints. The connectivity forecast system 330 may also determine this through feedback received from other airplanes operating connectivity forecast systems 330, from Internet satellite providers, based on weather data received, or other information.

Accordingly, portions 511 and 512 may include shading (e.g., lighter green or lighter red) or other colors (e.g., yellow) that indicate less than full or substantially full Internet availability based on the calculations performed using interpolation algorithms or other data.

Referring to FIG. 6, shown are coverage cells 521 and 522 covering a geographical regions. The coverage cells overlap each other. If an area is covered by a service available coverage cell 521, the displayed connectivity visualization map 500 indicates that service is available in the area. If an area is covered only by a service unavailable coverage cell 522, connectivity visualization map 500 indicates that service is not available in the area. The flight path may be formed through service available coverage cells 521 and service unavailable coverage cells 522. The portion of the flight path, which is not covered by any service available coverage cells 521 is marked with a dashed line 512, while portions of the flight path, which are covered by at least one service available coverage cells 521 are marked with a solid line 511. The dashed portion 512 of the flight path indicates that satellite Internet services are not available while the aircraft 540 flies along the portion 512 of the flight path. The solid portion 511 of the flight path indicates that the Internet services are available while the aircraft 540 flies along the portion 511 of the flight path.

For more accurate calculation of the service unavailable flight path 512, the connectivity forecast system may use interpolation algorithms to generate intervening waypoints between waypoints. With the intervening waypoints, the points of the flight path that touch the boundaries of the service available and unavailable coverage cells may be more accurately calculated. As noted above, unavailable flight path portions 512 may include shading (e.g., lighter green or lighter red) or other colors (e.g., yellow) that indicate less than full or substantially full Internet availability. Additionally, based on the current location of the aircraft 540 and other flight information such as speed of the aircraft that can be obtained through communications with the flight deck system, the connectivity forecast system may be able to forecast approximate time period before reaching the service unavailable flight path. Therefore, users in the aircraft may be prepared for the disruption of the Internet services.

Referring back to FIG. 5, the connectivity forecast system of the disclosed invention may utilize multiple coverage maps 520 and 530. The multiple coverage maps may be provided by different service providers, or may be different data services or plans that may be provided by the same service provider. The flight operators may select different service providers or data services while flying over a certain region. The selection may be determined by the flight path integrated with the coverage maps to minimize chances in which no Internet service is available.

The connectivity forecast system takes the flight plans provided by flight operators and determines whether the flight path will take the aircraft through any areas known to be without coverage. In this way, the connectivity forecast system may provide the benefit of increasing availability of the Internet services along the flight path by selecting different service providers based on regions.

With reference now to FIG. 7, shown is a connectivity visualization map 700 in which the coverage map includes coverage cells 702 are shown as honey-comb shapes on a map. While the screen in FIG. 5 shows the first and second coverage maps 520 and 530, the screen in FIG. 7 shows one coverage map. The connectivity forecast system has the capability to store multiple coverage maps and couple the stored coverage maps with the flight plan. The flight path 704 is shown traversing multiple coverage cells 702 With reference now to FIG. 8, shown is a menu 802 (e.g., a drop-down menu) overlaying the connectivity visualization map 800 to select service providers or other data services. The menu 802 shows available Internet provider services that can be selected by a user. The available provider services may be provided by the same or different Internet service providers. As shown, the menu allows selection of spot beams; spot beams enable determination and visualization of the Internet coverage cells (e.g., 521 and 522) described herein. The non-spot beams may show less granular Internet coverage. The available services may be selected, for example, to review and compare service destruction regions based on the flight plan to minimize chances in which no Internet service is available.

With reference to FIGS. 4 and 14, the disclosed invention provides the connectivity forecast system 330 to provide users aboard aircraft with status of network services. The disclosed invention also provides method for providing users aboard aircraft with status of network services. The connectivity forecast system includes a non-transitory storage medium 332 to store executable instructions and one or more processors 331 to execute the executable instructions that cause the one or more processors 331 to perform operations based on the instruction. The connectivity forecast system 330 communicates with service providers 360, and may communicate with a flight operator. With reference to FIG. 14, shown is an embodiment of a method 1400 for forecasting availability of network services during flight. In order to provide the users with the status of the network services, a flight plan including one or more waypoints is retrieved, block 1401. From the flight plan, a flight path is generated, block 1402. The flight path includes the one or more waypoints. One or more service coverage data is retrieved from the service providers, block 1403. The one or more service coverage data is transmitted from the service providers 360 and the service coverage data may include a plurality of sub-coverage data.

In embodiments, in order to generate visualization of portions, or more granular portions, of the flight path in which service is not available or is not 100% available, intervening waypoints (additional coordinates) are calculated, e.g., using interpolation algorithms or other methods, block 1404. The intervening waypoints are additional coordinates with closer intervals than the waypoints provided with the flight path. The intervening waypoints may be added into the flight path in addition to the existing waypoints. The flight path including the waypoints and the intervening waypoints is coupled or combined with the service coverage data to generate an integrated flight path (i.e., the visualization of the flight path with availability and unavailability indicated), block 1405. The integrated flight path indicates service available and unavailable portions of the flight path. From the integrated flight path, service availability over regions is determined, block 1406.

The integrated flight path showing service availability is displayed on a map (e.g., on a visual display on flight deck of plane), block 1407. Alternatively, the information of the service availability may be emailed to the users at a predetermined time period. Displaying 1407 the integrated flight path may comprise receiving GPS data of the plane, determining the location of the plane on the integrated flight path, and displaying the location of the plane on the integrated flight path. The location of the plane on the flight path is preferably constantly updated during the flight. Periodically or upon receiving information from the service providers or other sources (e.g., feedback from other connectivity forecast systems 330), method 1400 may check to see if the service coverage data has been updated, block 1408. If the service coverage data is updated 1408, the updated coverage data is retrieved from the service provider or otherwise determined (e.g., calculated from other sources) and method 1400 may repeat processes 1403-1407 with the updated service coverage data. In this manner, the connectivity forecast system 330 may provide real-time updates of the Internet connectivity forecast Method 1400 may also periodically check to see if the flight plan/path has been updated, e.g., based on the connectivity forecast shown by the integrated flight path or based on flight controller commands (e.g., due to weather or emergency conditions), block 1409. If the flight plan/path is updated 1409, method 1400 may repeat as shown. In this manner, connectivity forecast systems 330 may update the integrated flight path displayed and the Internet connectivity forecast for the flight path in real-time.

The information of the integrated flight path may include portions of the flight path in which the network service is unavailable. The information may be displayed in the display device 335 of the connectivity forecast system 330. The service available and unavailable portions of the flight path may be shown with different color code or with different visual representations such as solid lines and dotted lines. The information may be sent to the users through emails at a predetermined time period.

The connectivity forecast system of the disclosed invention includes an advanced connectivity module where customers are able to monitor the heartbeat of the cabin in real time from anywhere in the world. Several attributes are implemented which include usage analysis, connectivity forecast and flight monitoring emails.

FIG. 14 depicts a workflow diagram illustrating processes for forecasting availability of network services from service providers.

FIG. 15 depicts an embodiment of the connectivity information displayed by the system and method of the invention, made available to users via an addressable web interface, in which a screen shot of a display, or page, showing the prioritized scheme for graphically displaying the availability of network services on a prioritized basis, by highest order of priority of service provider is depicted. In this example, a plurality of network service providers may be available along portions, or all, of the flight path, in which each such service provider is assigned a unique priority relative to the other available service providers. The assigned priorities may be based on any metric or parameter characterizing the service providers such as, by way of non-limiting examples, bandwidth of the network service provided, cost of the network service provided, security of the network service provided or any other desired service provider parameter. The system and method the invention is operable as described herein to identify and display the highest priority available network service provider for each segment of the flight path that has differing availability of service providers. In FIG. 14, a segmented flight path 1500 is depicted from a source point 1504 to a destination point 1505, displayed in flight path segments 1501, 1502 and 1503. In this example, first segment 1501 may have one or more network providers available. In this segment, as an example, the highest priority service provider available in a first segment 1501 may be a first service provider, such as, for example, Viasat Ka service, which is uniquely represented by a solid line. In the next segment 1502, Swift Broad Band, which is uniquely represented by a dashed line, may be the highest priority service provider available for that segment. In the next segment 1503, there may be, for example, no network service available, which, for that segment, is represented by a dotted line unique identifier for the “no service available” case. Each service provider may be represented on a segment the flight path by a unique identifier such as, for example, line color, line type (such as, for example, dotted, dashed or a unique combination of dots and dashes). Line weight or other unique identifier which may include the use of displayed symbols to identify unique service providers, when that service provider is the highest priority service provider available for that segment. As the aircraft moves along segmented flight path 1500 from source 1504 to destination 1505, along successive flight path segments, e.g. from 1501 to 1502 to 1503 as depicted in exemplary fashion in FIG. 15, other higher priority service providers may become available in a next segment, or, alternatively, the highest priority available service provider for a given segment may not be available due to the aircraft leaving that provider's coverage area and entering a subsequent segment, meaning that network service may transition to a lower power priority service provider if no higher priority service provider is available in the subsequent segment. In each segment the system and method of the invention may cause the flight path for that segment to be displayed, using the highest available priority service provider's unique identifier in that segment. And so on.

Thus, in the example shown in FIG. 15, the first segment of flight path 1501 is depicted in the unique identifier for Viasat Ka service, indicating graphically that, for that segment, Viasat Ka service is the highest priority service provider available for that segment 1501. For the next segment 1502 the segment of segmented flight path 1500 is depicted in a unique identifier for Swift Broad Band (or Swift BB) services, indicating graphically that, for that segment 1502, Swift Broad Band is the highest priority service provider available. For those segments in which no service is available, such as, for example, segment 1503 in FIG. 15, the flight path may be displayed using a unique “no service” identifier which may be a unique color or line type, line weight, or other unique identifier which may include the use of one or more displayed symbols. In this manner the aircraft flight path may be displayed as a series of segments in which each segment represents a portion of the flight path that expects service from the highest priority service provider available for that segment. A user of the system and method of the invention need only observe the segments as displayed on a display of the their electronic device to gain a quick understanding of which service provider is the highest priority service provider for any segment, and to visually relate the segment to geopolitical boundaries and other features displayed on the underlying map.

Still referring to FIG. 15 the flight path may be oriented from origin to destination. In an embodiment, the entire flight path from source to destination may be presented by a sequential series of contiguous segments such that the highest priority services provider (if any) is identified for each segment along the entire length of the flight path. Alternatively, in an embodiment, at least a portion of the total aircraft flight path may be presented by a sequential series of contiguous segments such that the highest priority services provider (if any) is identified for each segment along such portion of the flight path. In a further embodiment, whether the total flight path is displayed or just a portion of the flight path is displayed, the displayed segments indicating the highest priority services provider for each segment need not be contiguous.

Still referring to FIG. 15, during flight, the flight plan may be changed or updated for any number of reasons, including but not limited to weather conditions, aircraft conditions, crew or passenger requirements, airspace restrictions or other reasons. Also, during flight, the service coverage areas or sub-coverage areas of the service providers may change. The system and method of the invention may operate to monitor changes to the flight path, coverage and sub-coverage areas of the service providers during flight, and may re-determine, for such new or changed conditions and flight path segments, the highest priority service provider for the updated flight path segments. Accordingly, the displayed flight path segments may be updated to reflect the updated flight path and/or updated priority service provider for such updated flight path segments.

Still referring to FIG. 15, in embodiments, a legend or other arrangement of information 1506 may also indicate to a user a legend graphically depicting unique identifiers, such as line types, used to identify specific service providers in the segments, and also used to identify “no service available” in the segments.

Still referring to FIG. 15, in embodiments, a table of forecast coverage information 1507 for an upcoming, i.e. next, segment, such as time at which it is expected the flight will encounter the next segment, the distance expected to be covered over the next segment, the highest priority available service provider for the next segment, and the time at which it is expected the flight leave the next segment. Any or all of this information, in any combination, may be presented to the user, for example in table form, on a display of the system, or on page displayed via a web portal wherein a user of the system may use a computing device in wireless or wired communication with a processor of the system for the purpose of retrieving the display information described herein from the processor to display on the user's computing device. In the example shown, the aircraft currently is in segment 1502 with Swift BB service available, will enter a segment of no coverage at time +08:55 (indicating 8 hours 55 minutes into flight), will travel along the flight path for a distance of 399 nautical miles (NM) for a period of 50 minutes in the zone of no coverage, exiting the zone of no coverage at time +09:45 (indicating 9 hours 45 minutes into flight). Alternatively, the times indicated in table 1507 may be any relative or absolute time, such as Zulu time, or time in any time zone. The time of travel in a segment may be calculated by the system and method of the invention using average aircraft performance information for the specific aircraft type, which may be derived from the flight plan information or provided directly by a user using a human user interface such as a keyboard and monitor, touchscreen or other human interface that is in communication with a processor of the system. Thus table 1507 or its equivalents provide a user with information regarding service available, if any, for a next or upcoming segment.

The term “approximately” can be +/−10% of the amount referenced. Additionally, preferred amounts and ranges can include the amounts and ranges referenced without the prefix of being approximately.

The terms and descriptions used herein are set forth by way of illustration only and are not meant as limitations. Those skilled in the art will recognize that many variations are possible within the spirit and scope of the invention and the embodiments described herein.
